Meeting Abstract 26.2  Wednesday, Jan. 4  Revaluating spiral-like cell cleavage patterns during the embryonic development of phoronids and brachiopods. SANTAGATA, Scott; Long Island University scott.santagata@gmail.com Embryonic patterns in cell cleavage and blastomere arrangements continue to be used as phylogenetically informative characters. However, cleavage patterns are clearly subject to evolutionary modifications especially among the various phyla that exhibit […]

Meeting Abstract 26.5  Wednesday, Jan. 4  Life History Evolution: Insights from Comparative Development and Gene Expression in Sipuncula BOYLE, M. J.*; RICE, M. E.; Smithsonian Marine Station at Fort Pierce, Florida boylem@si.edu Marine invertebrate animals develop through some of the most diverse life history patterns on earth, but how those patterns evolve is a mystery. We are […]

Meeting Abstract 26.3  Wednesday, Jan. 4  Darwin in a nutshell – the subtle intracapsular survival of the fittest in the common whelk Buccinum undatum SMITH, K E*; THATJE, S; University of Southampton; University of Southampton Kathryn.Smith@noc.soton.ac.uk Life history theories suggest parental fitness is maximised by investing equally into all offspring. The common whelk Buccinum undatum shows large […]

Meeting Abstract 25.5  Wednesday, Jan. 4  Genomic dynamics in a growing filamentous fungus ROPER, M.L.*; SIMONIN, A.; LEEDER, A.; GLASS, N.L.; UCLA; UC Berkeley; UC Berkeley; UC Berkeley mroper@math.ucla.edu The syncytial cells of filamentous fungi may harbor tens, thousands or even millions of genetically diverse nuclei within a single shared cytoplasm. This genetic diversity is acquired by […]
